Treatment gun

Abstract

The invention relates to the technical field of dry ice treatment equipment, in particular to a treatment gun. The treatment gun comprises a gun head, a gun shell, a switch, an air pipe, an LED warning light and the like. A flow valve used for controlling the flow rate is mounted on a sprayer of the gun head. The flow valve is made of low temperature resistant materials such as low temperature steel. A protection frame is further arranged in front of the flow valve and at the front end of the gun head. A temperature sensor is further arranged in front of the gun head and behind the protection frame. The temperature sensor and the LED warning light form a feedback control and indication system. The treatment gun solves multiple use problems: the flow valve controls pressure and flow of ejected liquid; by the adoption of low temperature resistant materials, it is not easy to cause crack; the non-closed circular arc protection frame does not affect the function of each part and can conduct comprehensive protection; the non-contact temperature sensor can be used for measuring both the temperature of a skin treatment point and the ambient temperature of the treatment point; through arrangement of the feedback control and indication system, prevention and control of treatment time, the best skin treatment temperature and over low skin temperature are achieved.

Description

technical field [0001] The invention relates to the technical field of dry ice treatment equipment, in particular to a treatment gun. Background technique [0002] Postoperative pain is a response of the body to surgical injury (tissue damage), including a series of physiological, psychological and behavioral responses. In clinical nursing work, pain has become the fifth vital sign following the four vital signs of body temperature, pulse, respiration, and blood pressure, and has received increasing attention. The pathophysiological changes of the body caused by postoperative pain should not be underestimated. It not only changes the circulation, breathing, digestion, endocrine, immune, blood coagulation and other systems, but also severe pain can cause mental trauma, which can bring anxiety, fear, insomnia, Helplessness. The current pain nursing measures mainly include drugs for pain relief (morphine, meperidine) and analgesic pump for pain relief. The continuous use of ...

AI Technical Summary

Problems solved by technology

Disadvantages: Temporary nerve block occurs, and cold injury needs to be repeated; the cold probe is large, and the percutaneous process will be uncomfortable; the success of the block depends largely on the closeness of the puck to the nerve

Disadvantages: expensive equipment; operators need to be trained and have certain work experience

[0011] (1) CO 2 When the liquid flows and when the dry ice is sprayed, strong shocks and vibrations often occur, which will affect the therapeutic effect and may cause safety hazards; in addition, liquid CO 2 From high pressure to normal pressure, it will be transformed into solid CO 2 (i.e. dry ice), with a temperature of -78°C, it will absorb a lot of heat from the surroundings. The nozzle and its upper components often alternate between low temperature and normal temperature. However, the flow valve commonly used on the pipeline cannot meet the needs of use and is prone to cracking due to thermal stress. ;

[0012] (2) During transportation and placement, the gun head directly touches other objects, which will have a certain impact on the performance of the treatment gun, and the more precise the parts, the more protection is needed, and it must also be ensured that the gun head will not be affected. Operation, this problem urgently needs to be solved;

[0014] (4) The treatment gun sprays dry ice directly onto the surface of the human skin to rapidly cool down the skin temperature. As a medical device, there are no good risk control measures in the prior art
